SPECIFICATION forming' part 0f Letters Patent No. 672,650. dated April.23, 1901.

Application iled December 20, 1900- e'erial No.' 40,503. (No modelV'have invented n ew and useful Improvements in Miners Sqnibs, of whichthe following is a specification.

' f My invention relates to minerseqnibs, the same residing in a novelconstruction of the squib itself and of the blank from which theY squibis made;

. pletion. A

tube completely formed, wit-h the outer edge` lheobject of the inventionis to provide a sqnib and the blank from which the same is produced bymeans of which the squib-tnbe is effectively closed at its forwardend-and by means of which the fuse or match is formed integral with thesaid tube and projects outwardly therefrom at a short distance from theend of said tube, so that in the event of a puncture of the forward endof said tube the explosive material contained therein will not fall uponand adhere to said match or fuse.

lOtherobjects of the invention will `hereinafter appear and the novelfeatures thereof will be set forth in the claims.

Inthe drawings forming a. part of this specification, Figure 1 is a faceview of the blank from which my improved squibis made. Fig. 2 is aperspective view of the same, showing one edge of the blank rolled kupona mandrel as the first ste in the formation of the tube. Fig. 3 is asim'lar view showing the closingiiap for the forward end of thesquib-tube g Fig. 4 isa similar view of the blank, illustrating thetube-forming operation near its com- Fig. 5 is a similar view showingthe thereof pasted or otherwise secured in place. Fig. 6 is aperspective view showing the match orfuse in its twisted condition, andFig. 7 is a similar view of the completed squib. Like reference-numeralsindicate like parts in the different views.

The blank 1 is provided withfthe. parallel side edges 2 3`and with atongue 4. and a lip or ap 5 at its forward end. The flap 5 is producedby a lateral incision 6, extending inwardly from the side edge 2 of theblank, by a longitudinal cut 7, parallel to the side edge 2 andintersecting the incision 6, and by an angnlarly-arrauged incision 8,the latter forming one of the side edges of the flap' and a portion ofone of the side edges of the tongue 4. The incision S terminates at itsrear end beyond the-incision 6, as Shown at 9, for a purpose which willpresently appear. The side edge 10 of the tongue 4 directly op- 4positethe incision 8 extends at an angle to 6o Said incision and terminates atits rear end beyond the end of the incision 8,*as shown at 1l., From thepoint 1l to the side edge 3 of the blank the material thereof is cutaway, as shown at 12. The lateral incision 6, extending inwardly fromthe sideedge 2 of the blank l, constitutes a guidefor the end of themandrel 13, upon which the blank 1 is rolled to form the squib-tube 14.In forming,r the squib-tnbe the cylindrical 7o mandrel 13 is placed uponthe upper surface of the blank 1, along the edge 2 thereof, with the endof said mandrel opposite the incision 6 `in said blank. The edge 2 isthen rolled upon the mandrel, as illustrated in Fig. 2 of 75 thedrawings, until the partially-formed tube comes opposite the [lap 5adjacent tothe longitudinal cut 7, which constitutes one of the sideedges thereof. The said flap is then folded inwardly, as shown in Fig. 3of the 8o drawings, closing the outer end of the partially-formedsquib-tube, andthe rolling of the blank upon the mandrel 13 iscontinued. 'lhis action causes the bent-in flap' 5 to be rolled betweenthe body of the blank l. and

the outer sui-face of the partially-formed The saine is thereby securelyheld in place, and dangcrof accidental separation thereof from the endof the squibftube is prevented. In Fianet of the drawings the 9o lip orfiap 5 is shwnhs completely iuclosed and covered by the partially formedtube; but the rolling),l of the blank lriupon the mandrel 13 iscontinued until the-edge 3 of said blank approaches said mandrel.Theupper surface of theblank 1, a-djiicont to the edge 3, .then hasapplied to it paste orother adhesive material, and when the` blankisciompletely rolled upon the mandrel 13, as illustratedin Fig. 50E thedrawings, the squib-tube is comloo pletely formed, with the edge-3 ofthe blank 1 pasted or otherwise secured in place. The

tongue 4has during this operation remained in practically dat condition,except, perhaps, along the line of its juncture with the body of theblank l. As the point 9, however, which is the rear end of the incision8, is back of the incision (5, which is in line with the frontend of thetube 1.1, it will be observed that the point orlinc ofjuncture of thetongue t with the body of the blank 1 is back of and .sligl'i'tlyremoved from the forward e'nd of the squib-tube. The point 1l, whichconstitutes the roar ond of the side edge 10 of the tongue 1, isslightly to the rear of the point 9, so that the line of juncturebetween the tongue 4 and the body of the blank l is a diagonal one. 'lhcresult of this construction is that when the tongue 4 is twisted to formthe match or fuse l5 the same will connect with the body of thecompleted sqnib at a short distance from the forward end thereof. Byextending the side edge 10 of the tongue at back to the point l1., whichis located to the rear of the point 9, said tongue when thearticle is inthe condition shown in Fig. 5 of the drawings will project slightly atan angle from` the squib-tube and the twisting action upon the tongue 4will have a tendency to roll said tongue around the projecting end ofthe squib-tube instead of at an angle, as shown in Figs. 6 and 7.

Of course after the mandrel 13 has been removed froin the tube which wasformed thereon the said tube is filled with powder or other explosivematerial andthe rear end thereof closed in any suitable manner. Now itwill be observed that as the closi 11g-flap 5 is folded inwardly overthe forward end of the partially-formed squib-tube and afterward rolledaround the forward end of said tube said tube is' completely andeffectively closed at its front end and none of the explosive containedtherein can escape except by punctu ring said closed end. In theevent-of suchgy puncture, however, and the consequent escape of thepowder or other explosive material from the forward en'd of thesquib-tube none will come in contact with or adhere to the match or fuse15, owing to the fact that said match o'r fuse is out of line with thebodyv of thesquib. An

eiective closing of the tube isfthereby formed by my construction, -aswell Aas an eiective means for preventing accidents due to the escape ofthe explosive material'frn the tube. The blank 1 may be made oftissue-paper or other suitable material, and the match or fuse 15 mayhave paraffin or other vsuitable slow-burning combustible materialthereon. Having now described my invention', what l vI'elaim as new, anddesire to secure by Letters Patent, is-

1. A miners squib having the match or fuse thereof secured to andprojecting from the thereof, and coated with paraffin.

Grasso tube at a point4 removed from the forward end thereof.

2. A miners squib having the match or fuse thereof secured to andprojecting from the tube ata point removed from the forward end thereof,and extending out of line with Said tube.

' 3. A miners squib having the match or fuse thereof integral with thetube and connected thereto at a point removed from the forward endthereof.

4.-. A lniners squib having the match or fuse thereof integral with thetube and extending ont of line therewith.

5. A minet-s squib having the match or fuse thereof integral with thetube, the line 'of juncture between said match and tube being diagonallyarranged. i

6. A blank for a miners squid having at one end thereof, a tongue forthe formation of the match or fuso, and a closing-flap, therear end ofthe edge of said tongue adjacent to said flap lying at-'a point back ofthe rear end of the opposite edge of said flap.

7. A blank fora minerssquib having at one end thereof a tongue for theformvtion ofthe match or fuscand a closing-flap, the said liap beingformed by a lateral incision leading inwardly from one of the side edgesof said blank, by a longitudinal. cut intersecting said incision and bya longitudinal incision Icoincident with one of the side edges of saidtongue, said longitudinal incision termina-ting at a point to the rearof said lateral incision.

8. A blank for a miners squib having at one end thereof a tongue for theformation of the match' or fuse, and a closing-flap, said iiap beingformed by a lateral incision leadinginwardly from one of theside edgesof said blank, by a longitudinal cut intersecting 4said incision and bya longitudinal incision coincident with one of the side edges of saidtongue, the said longitudinal incision terminating at a point to therear of said lateral incision, and the side of said tongue opposite saidlongitudinal incision being formed by a cut-away portion of said blankand terminating at a point to the rear of the end of said longitudinalincision. 9 A miner-s squib having the match or fuse thereof secured toand projecting from the tub at 'a point removed from the forward end Intestimony whereof I have hereunto set my hand in presence of twosubscribing witnessest EVAN'REESE.
